I've been using the Smitty carrier you linked above for over a year now with no problems. When I bought it, I researched it and nobody had anything bad to say about it. I bought it intending it to be a temporary solution. My only complaint is that it rattles when I go over big bumps. Other than that, it's been great.
My top two choices for an eventual replacement are the Teraflex or the OR Fab which are stand alone carriers that will let you use any bumper you like. I think the Teraflex carrier might work well when combined with this Smitty carrier. Teraflex sells two parts: The hinge and carrier. Supposedly you only need the hinge for a 35". I figure I will probably be able to add the hinge and keep the Smitty as the carrier. You might want to look into the same thing since there will be nothing close in price range to that combo.
